(E)-Enynyldialkylboranes, thus obtained, gave regio- and/or stereospecifically defined corresponding conjugated alkynones by alkaline hydrogen peroxide oxidation, conjugated (E)-enynes by protonolysis with acetic acid, and conjugated enynes bearing an unsaturated group on the internal alkenyl carbon atom by bis(acetylacetonato)copper-catalyzed cross-coupling reaction with allyl bromide or 1-bromo-1-hexyne respectively
Novel benzamide derivatives of formula (I) wherein W1, W2, R1 to R7, R6, X and Y have the meaning according to the claims, are positive allosteric modulators of the FSH receptor, and can be employed, inter alia, for the treatment of fertility disorders.
